Proper toothbrush care is an important part of taking care of your oral health, says the American Dental Association (ADA). Check how much you know about your toothbrush:
True or False?
1. You should replace your toothbrush every six months.
2. Toothbrushes may harbor microorganisms.
3. You should regularly use a toothbrush sanitizer to kill microbes on your toothbrush.
4. Toothbrushes should be stored in closed containers to minimize microbe growth.
5. You should never share your toothbrush.
Answers:
1. False. Toothbrushes should be replaced every three to four months, or more often if the bristles become frayed.
2. True. According to the ADA, "We know that the oral cavity is home to hundreds of different types of microorganisms, therefore it is not surprising that some of these microorganisms are transferred to a toothbrush during use."
3. False. According to the ADA, "There is no clinical evidence that soaking a toothbrush in an antibacterial mouth rinse or using a commercially-available toothbrush sanitizer has any positive or negative effect on oral or systemic health." However, the ADA adds that people with certain diseases or who are at high risk of infection may want to take extra precautions.
4. False. According to the ADA, "A moist environment such as a closed container is more conducive to the growth of microorganisms than the open air."
5. True. According to the ADA, "Sharing a toothbrush could result in an exchange of body fluids and/or microorganisms between the users of the toothbrush, placing the individuals involved at an increased risk for infections."
